ROBERT A, HART, OF WEST LIBERTY, PENNSYLVANIA.

PUNCHING-BAG APPARATUS.

To all whom it may concern:

Be it known that 1, ROBERT A. HART, a citizen of the United States of America, residing at West- Liberty, in the count-y of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Punching-Bag Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a bag punching apparatus, and the primary object of my invention is to provide an apparatus with noval bag supports that permit of a punching bag being placed in various positions on the apparatus, whereby the punching bag can be operated upon from various positions to obtain different kinds of exercise.

Another object of this invention is to provide a punching apparatus that is adjustable, thereby permitting of an overhead punching bag being correctly positioned for exercise.

A further object of this invention is to provide an apparatus of the above type that is inexpensive to manufacture, capable of withstanding the vibrations to which it is subjected, and highly efficient for the purposes for which it is employed.

With the above and other objects in view, the invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein like numerals denote corresponding parts throughout the several views, in which Figure 1 is a perspective view of a punching bag apparatus, Fig. 2 is an enlarged rear elevation of a frame and strike plate, Fig. 8 is a vertical sectional view of the same, Fig. 4 is a front elevation of a de tached strike plate, Fig. 5 .is a side elevation of the same as connected to a support, Fig. 6 is a horizontal sectional view of a portion of the apparatus illustrating the adjusting mechanism, Fig. 7 is an enlarged sectional view of a bag hanger, Fig. 8 is an enlarged elevation of a modified form of bag hanger, Fig. 9 is a longitudinal sectional view of the same, and Figs. 10 and 11 are enlarged perspective views of parts of the modified form of bag hanger.

An apparatus in accordance with this invention comprises a platform 1, preferably Specification of Letters Patent.

rectangular in plan. The plat-form 1 is sup ported in an elevated position by legs 2 arranged at the corners of the platform. The legs 2 have the ends thereof provided with sockets 3, said sockets being secured to the platform 1 and to the floor upon which the apparatus is placed. The lugs 2 are provided with T connections 4 and the Ts are connected by transverse braces 5 that have cross connections 6 adjacent to the Ts 4. The cross connections 6 vertically aline with openings 7 in the platform 1, and extending through the connections 6 and the openings 7 are uprights 8. The lower ends of the uprights have elbows 9 connected by transverse braces 10. The braces 10, intermediate the ends thereof, are connected by a longitudinal rod 11 and attached to said rod, intermediate the ends thereof, is a chain or cable 12.

The braces 5 have cross connections 13 intermediate the cross sections 6, and revolubly mounted in the cross connections 13 is a shaft 14 to which the chain 12 is attached and adapted to wind thereon. One end of the shaft 14 has a hand wheel 15 that is provided with a spring pressed pawl 16 engaging a rack 17, carried by the cross c011- nections 13 adjacent to the hand wheel 15. The pawl 16 and the rack 17 are employed for locking the shaft 14 against rotation, after the uprights 8 have been adjusted.

The upper ends of the uprights 8 are provided with elbows 18 and arranged in said elbows are the ends of converging supports 19 that have the inner ends mounted in sockets 20, carried by the periphery of the circular support 21. The support 21 is lo cated centrally above the plat-form 1 and has a central circular opening 22, said opening having the annular wall thereof provided with a seat 23 for a circular strike plate 24. The strike plate 24 is retained upon the seat 23 by clips 25 pivotally connected to the support 21, as at 26. The clips are diametrically opposed and prevent accidental displacement of the strike plate 24 relatively to its support. The rear side of the strike plate 24 has oppositely disposed handles 27 and oppositely disposed sets of resilient clamping arms 28, that permit of the strike plate being connected to one of the uprights 8, as shown in Fig. 5.

The front side of the strike plate 24 has a central bag hanger, comprising a plurality of converging arms 29 that has the ends thereof connected by a circular head 30. The head 30 has a central opening 31' for a revoluble sleeve 32, and mounted upon -the inner end of the sleeve 32 is a collar 33 that retains the sleeve in engagement with the head 80. The collar 33 is screwed upon the sleeve 32 and is locked thereon bya set screw The outer end of the sleeve 32 has a rounded off flange or bead 35 and said sleeve receives the suspension string or strap 36 of a punching bag 37, said string or strap having the end thereof knotted to retain the same within the sleeve 32.

A set of the uprights 8 have Ts 38 provided. with arms 39 that are connected to a circular support 40, similar to the support 21. The support 40 is vertically disposed and the lower edge thereof has a socket 41 nectedfor various kinds of exercises, and

in order to add rigidity to the upright 8 during exercise, the uprights are braced by l The tie rods 45 are diagonally disposed and do not tie rods 45 and turn-buckles 46.

interfere with an adjustment of the uprights 8 which as shown in Fig. 1, are in their lowermost position.

Fixed upon one of the supports 19 by set screws 47- are'collars 48 and movably arranged between said collars is a sleeve 49 that is formed integral with a socket 50 for the string or strap 86 of the punching bag 37." The punching bag 37 can therefore be attached to one of the supports 19, whereby it will swing completely around said supports when it is desired to obtain such eX- Ic)rcise that is accomplished by punching the From the foregoing it will be observed that I have devised an apparatus wherein a stationary platform is provided with an adjustable framework for supporting a punching bag in various positions, whereby it can be easily operatedjupon. The

framework, as illustrated, is made of tub-' ing or gas pipes and providesa strong and durable structure.

While in the drawings there are illustrated the preferred embodiments of the invention, it is to be understood that the structural elements are "susceptibleto such Copies of this patent may he obtained for Washington, I). 0.
